//题目：一个5位数，判断它是不是回文数。即12321是回文数，个位与万位相同，十位与千位相同。
//1.程序分析：同29例
//2.程序源代码：
#include "stdio.h"
int main() {
	long ge, shi, qian, wan, x;
	scanf("%ld", &x);
	wan = x / 10000;
	qian = x % 10000 / 1000;
	shi = x % 100 / 10;
	ge = x % 10;
	if (ge == wan && shi == qian)/*个位等于万位并且十位等于千位*/
		printf("this number is a huiwen\n");
	else
		printf("this number is not a huiwen\n");
}
